Well those were all DC so these are my AC readings. I pulled the plugs to do a compression test and all cylinders are between 110 and 118 but cylinder 4 (second down port side) looks like it has never fired but was wet.

I have no idea what I am seeing.

Let's start over.

Disconnect the brown wire terminal and the red wire terminal from the CDI box. Attach your volt meter to the terminals. One probe to the brown wire terminal and the other probe to the red wire terminal. Voltmeter set on AC. Pull the kill switch lanyard so that the motor won't start. Crank the motor for 5 seconds while watching the volt meter. What is the voltage that you see?

Why would you set the meter on DC when you are measuring for AC voltage?

Yep I definitely had the wrong approach. I'll answer back when I get back on it this weekend.

It wasn't on purpose. I ran outside while my newborn daughter was napping and ran the wrong setting in a rush.

Ok so with the red and brown leads unhooked from the cdi and voltmeter set to 200v AC I saw a max reading of 2.5v

And did you check both wires to verify that neither is unintentionally shorted to ground?

The leads where voltage was measured were completely separated and wrapped to be sure. As far as I could chase the wires up the flywheel didn't look damaged either.

Set the multimeter on the continuity setting. Connect a probe to the brown wire. Connect the other probe to the block. There should no continuity.

I thought the meters showed an OL when there was no continuity.
at least mine do that.
a 1 would mean 1 ohms of resistance ( not good)
Mine reads 1 with no connection. If I touch the probes

I see a 1 one the left side with no continuity and three digits on the right when there is.

With the dva hooked up to the brown and red leads I saw 6.8v with the meter set to AC 200v.

did the DVA come with instructions on what to set the meter to, to get the readings?
I thought it was to DCV.

but it sure looks like you low speed charge coil is not putting out what is should be

There weren't any in the box and this wasn't the cheapest one by far. I'll find some directions and post back.

also looking at your pics it looks to me that you have the meter set to diode testing not ohms settings when doing continuity testing

When set to DCV I am seeing 3.06v

was that with you spinning the motor over with the starter?
